Using factoring, which values are the solutions to the quadratic equation 2m2+7m−30=0?

Luden [163]

Answer:

B: m = -6 or m = 5/2

Explanation:

$\rightarrow \sf 2m^2 +7m - 30 = 0$

breakdown

$\rightarrow \sf 2m^2 +12m -5m- 30 = 0$

take out common factor

$\rightarrow \sf 2m(m +6) -5(m+ 6) = 0$

collect into groups

$\rightarrow \sf (2m -5)(m+ 6) = 0$

set to zero

$\rightarrow \sf 2m -5=0, \ m+ 6 = 0$

change sides

$\rightarrow \sf m=2.5, \ m= -6$

rodikova [14]

Answer:

Roasted Steak RS=14.47

Grilled Salmon GS= 25.21

Step-by-step explanation:

It's a 2 equation system as follows

E1-> 17RS+14GS=598.95

E2-> 28RS+7GS=581.64

We assume the system has only one solution and apply the following calculation to create a single equation

E3 -> 2x E2 -E1

That way the only incognit will be RS

(28x2 - 17) RS + (7x2 - 14) GS = 581,64x2- 598,95

39RS= 564,33

We solve for RS and then use E1 to solve for GS and E2 to check the answers
